CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 481907, dated August30, 1892.

Application filed May 27, 1890. Renewed April 13, 1892. Serial No.&28,983. (No model.)

To all whom it may concern:

Be it known that I, JEFFERSON KINDLE- BERGER, a citizen of the UnitedStates, and a resident of the city and county of San Diego, State ofCalifornia, have invented new and useful Improvements in Car-Couplings;and I hereby declare that the following is a clear, full, and exactdescription of the invention, that will enable others skilled in the artto which it appertains to make and use the same.

My invention relates to improvements in car-couplings, the object ofwhich is to make it possible to add my improvements to the ordinarydraw-head now in common use, as will be hereinafter fully described andclaimed, reference being had to the accompanying drawings, in which-Figure 1 is a longitudinal section of two draw heads, showing my couplerapplied thereto. Fig. 2 is a top plan View of the tongue. Fig. 3 is aside elevation of the tongue and connecting parts. Fig. 4: is an endView of the draw-head showing my improvements secured therein.

Referring in detail to the various parts of my invention, A is thedraw-head, which is constructed in the usual manner or any preferredstyle and provided with the interior throat or hollow space, in which isarranged the tongue B, having a sufficient length to reach from theouter to and through the rear end of the draw-head, as shown in Fig. 1.The outer end of the tongue is provided with the arrow-shaped head C,having the angular shoulders c, which form the engaging-surface of thecoupler When in use. The rear end of the tongue passes entirely throughthe inner end of the draw-head and is there secured by the bolt b, asshown in Fig. 2. The shoulders c are on a line with the outer surface ofthe draw-head.

In order to efficiently control the coupler, I mount in the tongue B theoblong cam D, the plane of whose body is normally at an angle of aboutforty-five degrees with the plane of the tongue, and as each of thetongues are thus equipped with cams pivotally secured in the opening b'it will be readily understood that their ofi lce is to separate the endsof the tongues when they are joincd toge'ther by the angular shouldersc, as shown in Fig. 1. The cams D are controlled by the transverse shaftd, having the upwardlyreaching arm d', preferably connected by a chainto the standard E, erected to the upper side of the draw-head or uponthe edge of the platform of the car, as preferred. The tongue Bnormallylies upon the floor of the opening in the draw-head and is heldin this position by the spring F, the inner end of which is suitablysecured to the upper side of the in terior of the draw-head, while itsend is properly bent to rest against the tongue when the same is restingupon the lower surface of the throat of the draw-head.

In operation the cars provided with my coupler are brought together inthe usual manner, and when so brought together the tongues B with theirpointed ends engage with each other, either of which may pass on top 'ofthe other until the upper one shall drop down behind the shoulders c,When the coup-.

ling is efifected. It will be seen that the cam of one tongue is in anoperative position against the head of the other tongue, and by a pullof the chain attached to the arm d' said cams will so act upon the headsthat they will readily and easily separate the same and will thusuncouple the cars. The draw-head is provided in the usual manner withthebufier or cushiou spriugs G.

It will be seen that I have provided a simple and effective means forefficiently attaching one car to another, which also enables theoperator to readily uncouple the same, and believing that furtherdescription is unnecessary for a clear comprehension of the various Idetails, I will now specifically set forth my claims.

Having thus described my inveintion, what I claim, and desire to secureby r letters Patent, is-

1. A car-coupler consisting of the drawhead A, the arroW-headed tonguessecured therein, the cams mounted in said tongues and operated by thearm d', the spring F, secured to the upper side of the draw-head andarranged to hold the tongue against the lower side of the draw-head',substantially as described.

2. The combination of the draw-head, the tongues passing through thesame and se- IOO eured at its inneend by the bolt b, as shown, whle theother end thereof is provided With the ponted ends having the shouldersc, the cams mounted in the tongnes near the head the'eof, the arm b',connected with the standard E by the operating ehtin, and the spring F,Secured to the upper side of the d raw-head, as set forth.

3. The eombinaton, With a railway-car, of the drJW-head A, provided withthe tongue B, the spral spring G, the oblong cam D, pivotelly mounted inthe tongue and adapted to press against the head of the other tongue andJEFFERSON KINDLEBERGEK.
